According to the U.K.-based WITT Energy website (witt-energy.com), "The WITT is the only device in the world that can capture energy from all movement and turn it into electricity. No other energy system can exploit the full spectrum of movement, enabling it to harvest power from water (sea, river or tidal),
wind and human or animal motion."
This is a very exciting year for AGMA as the organization celebrates its 100-year anniversary. In addition to the anniversary, AGMA President Joe Franklin, jr., who has done an outstanding job at the
helm of AGMA for the last 25 years,
will retire, and we welcome in our new
AGMA President, Matt Croson, who will
lead us into the next 100 years. The centennial kicked off in October with a dinner at the AGMA Gear Expo in Detroit and will continue throughout 2016 with a number of exciting events scheduled to celebrate this milestone anniversary.
With the ongoing push towards electric vehicles (EVs), there is likely to be increasing focus on the noise impact of the gearing required for the transmission of power from the (high-speed) electric motor to the road. Understanding automotive noise,
vibration and harshness (NVH) and methodologies for total in-vehicle noise presupposes relatively large, internal combustion (IC) contributions, compared to gear noise. Further, it may be advantageous to run the electric motors at significantly higher rotational speed than conventional automotive IC engines, sending geartrains into yet higher speed ranges. Thus the move to EV or hybrid electric vehicles (HEVs) places greater or different demands on geartrain noise. This work combines both a traditional NVH approach (in-vehicle and rig noise, waterfall plots, Campbell diagrams and Fourier analysis) - with highly detailed transmission error measurement and simulation of the complete drivetrain - to fully understand noise sources
within an EV hub drive. A detailed methodology is presented, combining both a full series of tests and advanced simulation to troubleshoot and optimize an EV hub drive for noise reduction.
under pressure from numerous
market forces. The oil sector's
decline, weakened global economies
(particularly China) and local government policies outnumber and outweigh relieving forces such as the FAST Act, leaving the industry in a general downturn. The outlook has yet to become truly grim, but companies are beginning to scale back.
AGMA President Joe Franklin is stepping down after some 24 years on the job. He graciously took the time to answer some questions from Gear Technology Senior Editor Jack McGuinn regarding his tenure.
